Chimba is a very popular slang word in Colombia that can mean 'cool,' 'awesome,' or 'great.' While it can sometimes be used negatively depending on the context, here Maluma uses it to express how amazing his time with his ex was.
He sings, "qué chimba la pasábamos" which translates to "we had such a great time." Learning slang like this is a fantastic way to understand the culture behind the language and sound more like a native speaker!
In "Procura", Colombian reggaeton star Maluma plays the classic role of the confident ex who just checked his former lover's social media and is not buying the hype. He spots her posting captions like "Por fin encontraste alguien que te quiere... no como esos que abandonan" ("You finally found someone who loves you... not like those who abandon you"), and immediately calls it out as a passive-aggressive indirect hit directed right at him. His response is blunt: "Procura no pensar en mí cuando estés en su cama" ("Make sure not to think of me when you're in his bed"), while admitting he has the exact same problem whenever he tries to move on with someone else.
The track is packed with Colombian flavor and smooth cockiness. When Maluma reminisces about their past, he drops authentic Medellín slang, singing "qué chimba la pasábamos" ("what a great time we had"), where chimba means something was fantastic or cool. He also refers to his suave persona, telling her "Vente con Don Juan" ("Come with Don Juan"), asking her to drop the online act because they both know she still craves their old romance over a glass of wine.
